Has some significant performance improvements, another large SPSA tune, and support for the Fischer random chess variant.
For the sake of my sanity (and because .NET can't/doesn't autovectorize NNUE code), this requires AVX2.
Picking a binary:
The Lizard-...-x64-aot binary will almost certainly be the fastest, but you might need to compile it yourself on your own hardware.
Otherwise, use the Lizard-...-x64-pext binary if you have a modern processor.
If you don't have PEXT, or have an AMD processor older than Zen 3, you should probably use the non-pext Lizard-...-x64 binary. It might be worth trying both though because of how different processors handle PEXT.
